RAILROAD-TIE;

Italy, have invented certain new and useful ImprovementsinRailroad-Ties, of which the following is a specification.

- My invention relates to a railroad tie and has for its object theconstruction of a tie of cement or similar composition in such*manner'as to eliminate the defects common to thatkind of tie, saiddefects consisting [principally in the di'l'liculty of obtaining a seatfor the rail which shall be rigid and at the same time su'liicientlyelastic as not to injure the rolling stock and cause anexcessive'vibration of the road.

. 5 which constitute seats for the rails.

The inventionwill be understood by reference to the accompanying(.lrawings in which Figure 1' is a plan view of a tie-with the railssupported upon it; Fig. 2 a vertical longitudinal section on the planeof the line 22 of Fig. l; Fig. 3 a transverse. vertical section on theplane of the line 3 3 of Fig. 1 Fig. 4 a-longitudinal horizontal sectionon the plane of the line 4--4 of Fig. 2; Fig. 5 a horizontal section ofa modified form o'l' block; and Fig. 6 is a view of one of the sets ofreinforcing rods.

Similar reference numerals indicate similar parts in the several views.

The tie as herein described is pre'l'erably made of cement or shnilarcomposition molded to the desired form and proportions. 'l hecentralbody portion] thereof isstrengthened by a longitudinal rib 2, and theend sections-3 have concave depressions 4 formed therein adapted toreceive blocks The said blocks are preferably of wood and the rails (5are secured thereto in any usual manner. ,The said depressions A areopenended, that is they extend transversely of the tie from side to.side and the side walls. thereof are longitudinally crmvergent', theblocks 5 being correspondingly formed so that said. blocks will befirmly wedged in position; When laying the ties care should be observedto so place them relatively to each other that the blocks 5oil-contiguous ties shall have their converging walls run- 5 tie in alongitudinal direction-Will be resisted.

ning inopposite directions. This will prevent any displacement of theblocks as a force tending to thrust the blocks of a given Specificationof Letters Patent. Patented Jan. 21, 1908.

by the blocks of the contiguous tie: de-

pressions 4 are made slightly concave, as shown in Fig. 2 so as to leavea s ace between them and the bottom of bodks 5.1

This feature gives a certain degree of flexi-v bility to the blocks thevibrations being transmitted to the side walls of'the depres sions.

Instead of making the blocks 5 of a single piecel may make them of twopieces 7, as indicated in Fig. 5, adapted to be held in position by akey or wedge 8. This-permits of an easier method of adjustment for theslight differences in the dimensions ofsthe blocks and the depressionsin the ties. The tie is reinforced by a series of iron rods 9 embeddedin the lowerpart thereof and running longitudinally, and by a seriesofcross rods 10 in the enlarged ends 3 below the depressions 4. A secondset of rods 11 eX- part thereof, The rods 11 have secured thereto,'inthe manner shown .in Fig. 6, short rods 12 inclined upwardly and havingtheir centers depressed to forin loops which surround the depressions 4to resist lateral tend longitudinally of the tie near the upper vthrusts of the block during the passage of trains. l l

If necessary to replace a block 5 1t 1S'S1l'llleicnt to remove the railholding spikes, when by a blow on the smallerhcad of the block it may beeasily pushed out of the depression, the construction permitting thisWithout the necessityof lifting the tics or disturbin the rails whichthey support. An additionai advantage is the lessening of the cost inas:7 much as the rail seat or block 5 is the only part requiring renewal. gT/Vhat I claim and. desire to secure by Let tors Patent is:-- I

l. A railroad tie having depressions therein extending transversely ofthe tie from side to side, the side walls of said depressions beinglongitudinally convergent, and correspondingly shaped blocks seated insaid depressions upon which the rails are adapted to be secured. '3. Arailroad tie having depressions;therein extending transversely of thetie from side to side, the side walls of said depressions beinglongitudinally convergent, and corre spondingly shaped blocks seated insaid dopressions'to which. the rails are secured, said,

tie being reinforced by rods embedded therein.

spondingly shaped blocks seated in-said dein, one series of said rodsbeing bent to form loops which surround said depressions.

pressions to which the rails are secured, the bottom of said depressionsbeing concave to providea space below said blocks.

In testimony whereof I have hereunto 15 signed my name in the presenceof two subscribing Witnesses.

3. A railroad tie having den ressions therein extending transversely oft e tie from side to side, the side Walls of said depressions beinglongitudinally convergent, and correp ressions to which the rails aresecured, said 7 me being remforced by rods embedded there GAETANO BOSSLWitnesses:
